Discussion

The UI_INFO_DLG_DEF_CLIENT_WIDTH() function tells you how wide the specified embedded Xdialog will be.

Example 

This script demonstrates how the size of a parent dialog box can be automatically calculated 'so that the embedded dialog box that it contains can be displayed correctly, without clipping 'any portion of the embedded dialog box.

list = a5.Color_Enum()
str = <<%dlg%
{nocaption}
[.100,5^#list];
%dlg%
w = ui_info_dlg_def_client_width(str)
h = ui_info_dlg_def_client_height(str)
ui_msg_box("Size of embedded dialog: ","width: " + w + crlf()+ "height : " + h)
dlg_body = <<%dlg%
{startup=init}
{embedded=w",h":window}
%dlg%
dlg_body = stritran(dlg_body,"h","" + h)
dlg_body = stritran(dlg_body,"w","" + w)
ui_msg_box("Parent Dialog Body - with placeholders for Height and Width replaced",dlg_body)
ui_dlg_box("Dialog Box with Embedded Dialog - Parent Dialog is correctly sized",dlg_body,<<%code%
if a_dlg_button = "init" then
       ui_modeless_dlg_box("window",str,"1=1")
end if
%code%)

In this example, the lastname prompt and the field are on separate lines (because of the semi-colon after lastname: ). The Xdialog will be 2.40625 inches wide.

? ui_info_dlg_def_width("lastname:; [.40name]")
= 2.40625
